Surefire UE-BK Replacement Rear Cap Assembly - Black - For Scout Light Weapon Lights

The SureFire UE-BK is a replacement rear cap assembly (tailcap) designed for the SureFire Scout Light weapon light series, including the M300 and M600 models. It threads onto the rear of the Scout Light body and houses the push-button activation switch.

The tailcap is machined from aerospace-grade aluminum and finished in Mil-Spec Type III hard-anodized black for corrosion and wear resistance in hard-use environments. The integrated switch features a .75" diameter cap and accepts SureFire remote tape switches, allowing the weapon light to be activated remotely for flexible placement on a rifle, shotgun, or other long gun.

A built-in lock-out feature positively prevents accidental activation during transport, storage, or operations, helping preserve battery life and eliminating the risk of unintended illumination. The UE-BK installs in place of a worn or damaged tailcap and brings a Scout Light back to factory-spec function.

This is a genuine SureFire UE-BK replacement part and an ideal spare for any user running Scout Light weapon lights in duty, defensive, or recreational roles.
